Drugs
|
Most common treatment of Sz Antipsychotics being taken in the form of syrup, injections or tablets. May be used in short term or long term |
|
|
Typical antipsychotics
|
Clorpromazine Dopamine hypothesis links Antagonists in the system, reducing the action of the neurotransmitter by blocking dopamine receptors in the brain Often used to calm patients |
|
|
Atypical antipsychotics
|
Clozapine binds to dopamine receptors in the same way but also binds to serotonin and glutamate. Improves mood and reduces depression Often given to suicidal Sz patients Fatal side effects so Risperidone introduced |
|
|
Evidence for effectiveness
|
Thornley et. al. placebo Showed that those taking drugs functioning was improved Support for benefits of atypical antipsychotics |
|
|
Fatal side effects
|
Long term use resulting in tardive dyskinesia caused by dopamine supersensitivity. Neuroleptic malignant syndrome, regulation of body systems prevented Atypical created to reduce these side effects but still need regular checks on blood |
|
|
Depends on dopamine hypothesis
|
Evidence to show that this explanation is not complete and mixed knowledge on whether Sz is caused by too high or too low levels of dopamine Modern knowledge suggests these drugs shouldn't work |
|
|
The interactionist approach
|
Acknowledges the influences of biological, psychological and societal factors in the onset of Sz Genetic vulnerability, stress and daily hassles |
|
|
Diathesis-stress model
|
Both a vulnerability to Sz and a stress trigger are necessary in order to develop the condition
|
|
|
Meehl
|
Original model Diathesis was completely genetic and the result of a schizogene If a person does not have this gene they will never have Sz |
|
|
Modern diathesis
|
Many genes increase vulnerability Psychological trauma also now causing vulnerability rather than being the stressor Severe trauma in young age causing HPA system to become overactive making stress more damaging |
|
|
Modern stress
|
Modern definition is anything that could trigger Sz Research into onset after usage of cannabis Cannabis interferes with the dopamine system |
|
|
Treatment
|
Combination of drugs and psychological treatments such as therapy
|
|
|
Evidence for the role of vulnerability and triggers
|
Tienari investigated vulnerability and parenting style Child rearing involving criticism and low empathy associated with Sz but only for those with genetic vulnerability |
|
|
Original model too simple
|
Multiple genes influence onset of Sz Stress can come in many forms Vulnerability a result of early trauma |
|
|
Support for effectiveness of combined treatment
|
Turkington et. al. said it is not possible to use combination treatment without accepting the interactionist approachCombination groups been proven to show less symptoms
